BRX Do-More PLC Dynamic Web Pages


We will now look at creating BRX Do-More dynamic web pages on our PLC web server. These pages are great for operator information display. A dynamic web page is a web page that displays different content each time it’s viewed. For example, the page may change with the time of day, the user that accesses the web-page, or the type of user interaction. There are two types of dynamic web pages.
Client-Side Scripting – Web pages that change in response to an action within that web page, such as a mouse, keyboard action, or timer, use client-side scripting. Scripting languages such as JavaScript will allow this updated content to your users.
Server Side Scripting – Web pages that change when a web page is loaded or visited use server-side scripting. Login pages, forums, and shopping carts are examples of server-side scripting. PHP, ASP, Perl, and ASP.Net, are some of the languages that can be used.
BRX Do-More PLC Dynamic Web Pages
Previously we enabling the HTTP web server, set the whitelist, and reviewed the website on our BRX Do-More PLC. We will be using JavaScript in our HTML web page to create dynamic content for our BRX Do-More PLC. These pages will be stored on the SD memory card and transferred to the RAM memory upon powering up our BRX Do-More PLC. Let’s get started. Continue Reading!

BRX Do-More PLC to Modbus TCP RTU Remote IO BX-MBIO

The BRX Do-More PLC can communicate to a remote I/O (input and output) controller modules using the Modbus protocol for communications. The BX-MBIO provides both Modbus RTU and Modbus TCP interfaces. Modbus RTU is a serial communication and Modbus TCP is an Ethernet communication. Modbus RTU is supported over an RS-485 serial connection. Modbus TCP is supported over an Ethernet connection. They function as listening/replying devices (slave, server) and can connect with any mastering (master, client) device that communicates using the Modbus protocol.
Previously we looked at the BX-MBIO Modbus RTU TCP Remote IO Controller wiring and configuration.

We will connect the BRX Do-More PLC to the Modbus remote IO. This will be done using the Modbus TCP and Modbus RTU protocol. Ethernet and serial RS485 communication to the BX-MBIO unit will be the media.
The BX-MBIO remote I/O expansion units feature the following:
• RJ45 Ethernet port for communications via Modbus TCP
• RS485 serial port for communications via Modbus RTU
• Supports up to 8 additional Expansion Modules (Add the discrete or analog I/O you require)
• AC and DC powered units available
• AC powered units include an integral 24VDC auxiliary output power supply
• Power connector and serial port connector included
Let’s get started. Continue Reading!

BRX Do-More PLC Analog Dusk to Dawn Program

A dusk to dawn sensor usually is discrete on/off of the lighting control. If we want to vary the lights to mimic more of the sunset and rise, we would use an analog output to control the lights. I was recently asked about such a program. Every day they wanted the lights to go off at 10 pm and come back on at 6 am. At 9:30 pm the lights would be on at 70% or 7volts of a 0-10V signal. In the next half hour, the program will bring the lights from 70% down to 0%. In the morning the lights will come back on within the half-hour from 0% to 70%. Poultry Farms are one place that would utilize this program.

We will be developing a program that will do this with our BRX PLC (Do-More). Let’s get started! Continue Reading!

BRX Do-More PLC HTTP JSON Instructions

We will now look at the BRX Do-More HTTP JSON instructions in the PLC. One of the features of the BRX Do-More Series PLC is the ability to expand its capability to fit your application. Software and hardware changes are ongoing so the PLC can grow with your needs. Communication is something that the BRX Do-More PLC can do very well. As part of the internet of things (IoT), the BRX Do-More will share and exchange data. You can also refer to this as the industrial internet of things. This will suit several industrial applications.
BRX Do-More PLC HTTP JSON Instructions
The Do-more Updates Release 2.5.2 on April 22, 2019, has introduced new instructions. Here are the instructions that we will be using:
HTTPCMD – HTTP Request / Response with Server (BRX only) Do-More
JSONPARSE – Parse JSON Text (BRX only) Do-More
We will be using these instructions to read the weather conditions from a website. Let’s get started. Continue Reading!
